Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with specific embodiments.

[0011] The invention provides a dual-tube dual-channel syringe, such as figure 1 As shown, it includes a needle tube 1. A needle 2 is provided at the front end of the needle tube. A first partition 3 is provided in the needle tube 1 along the length direction. The needle tube 1 is divided into a first cavity 4 and a second cavity by the first partition 3 5. The first cavity 4 is provided with a first piston 6, the first piston 6 is provided with a first piston handle 7, the second cavity 5 is provided with a second piston 8, and the second piston 8 is connected with The second piston handle 9, the second piston handle 9 is arranged on the outside of the second cavity 5; along the length direction, the needle 2 is divided into a third cavity 11 and a fourth cavity 12 by a second partition 10, the third cavity The body 11 communicates with the first cavity 4; the fourth cavit...

Abstract

The invention discloses a double-tube double-channel syringe and a needle head, including a needle tube, a needle head is arranged at the front end of the needle tube, a first partition is arranged inside the needle tube along the length direction, and the needle tube is divided into a first cavity and a first cavity by the first partition. In the second cavity, the first cavity is provided with a first piston, the first piston is provided with a first piston handle, the second cavity is provided with a second piston, and the second piston is connected with a second piston handle. The two piston handles are arranged outside the second cavity; along the length direction, the needle is divided into a third cavity and a fourth cavity through the second partition, and the third cavity communicates with the first cavity; the fourth cavity communicate with the second cavity. In the present invention, the separation of the first cavity and the second cavity but the design of the needle entering the same blood vessel realizes the relatively independent injection of hyaluronic acid and blood withdrawal, which effectively avoids the most serious complication of hyaluronic acid injection, vascular embolism, and can be performed effectively and safely. Hyaluronic acid injections allow doctors and patients to perform injections with greater confidence.

Description

Technical field [0001] The invention belongs to the technical field of medical plastic surgery, and specifically relates to a dual-tube dual-channel syringe, a dual-tube dual-channel syringe and a needle. Background technique [0002] At present, fillers (especially hyaluronic acid) injection microplastic surgery are very common, but adverse side effects occur from time to time. The most serious is vascular embolism. Vascular embolism can cause skin necrosis in the least, and blindness and even death. If the needle enters the blood vessel and injects hyaluronic acid, it will cause the hyaluronic acid to enter the blood and cause blood vessel embolism. At present, the most effective and easiest way to determine whether the needle has entered the blood vessel is to withdraw. If the blood is drawn back, the needle has entered the blood vessel. However, due to the thick texture of hyaluronic acid and the thinner needle of hyaluronic acid injection, the pressure problem cannot be rec...
